This has been around for about 3 years, maybe more. Was originally called X10 Version 2. Basically you can interogate the device to find out what it's state is so provides a more robust system where knowing something actually received and responded to the command is important. I did the garage door really close

In general terms if your mains circuity is in good condition then it does not offer much more. The big plus point is that after a reboot your control software can interogate all devices and know exactly what their state is rather than assuming devices are in the same state as they were before the reboot.

I'm from Australia as well & this stuff just caught my attention (Got the same email as wombiroller)will it work with LinuxMCE at the moment, or would some development be needed?

Yes the modules will work LMCE, the controllers are the same as what X10 v1 used so no different, if a module sends a status update then LMCE will respond to it if you have a CM11, or shortly to be supported CM15
